BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf tee,

The present invention relates to a method of manufacturing a golf tee using an eco-friendly natural material, and a method of manufacturing a golf tee for placing a golf ball at the time of a tee shot, in which a conventional wood is cut or a synthetic resin is pressed, It can be natural degradation by forming golf tee by using natural materials such as rice and minerals and natural adhesive composition to prevent environmental pollution, safety in use management, and increase productivity by cost reduction To a method of manufacturing a golf tee using an eco-friendly natural material.

In general, golf has been recognized as a high - end leisure sport, but recently it has become a popular sport as interest in health and diversity in leisure life have increased.

Tee shot is the tee shot of each hole in golf. It is called a golf tee, in which a ball is placed in a field like a nail to make it easier to hit the golf ball on the teeing ground. In the past, sand or soil was piled up on the field to put the ball, but now mostly made of wood or plastic Peg (Peg) type of golf tee is used.

However, a plastic golf tee made of synthetic resin as a raw material has a problem that most of the plastic golf tee is broken due to impact at the tee shot, so that there is a risk of hard and sharp debris, and scratches or the like are generated in the striking portion of the club head . In addition, since the fragments are scattered in the field, it is very troublesome to collect, and due to the characteristics of the synthetic resin, there is a problem that environmental pollution is caused by fragments that do not rot for a long time and safety of the field is deteriorated.

In order to solve the problems of the above patent, Korean Patent Laid-Open Publication No. 10-2004-0026893 discloses an acrylic golf tee manufactured by cutting an acrylic plate by hand. However, acrylic has a disadvantage that its strength is significantly higher than other materials, resulting in poor molding processability. Therefore, the manufacturing method of the above-mentioned patent is bound to limit, and rather, the problems with the increased strength are intensified.

In order to overcome these problems, recently, the use of golf tees manufactured by processing wood has been gradually increasing. However, since the cost of wood is high and the processing method is difficult to use as a raw material of golf tees near one-time consumables, There is another problem accompanied by an increase in cost.

1 is a flow chart showing a method of manufacturing a golf tee using an environmentally friendly natural material according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following description is given as an example for illustrating the principle of the present invention, and the present invention is not limited to the embodiments but can be implemented in various different forms. And throughout the specification, like reference numerals designate like elements.

1 is a flowchart illustrating a method of manufacturing a golf tee using an environmentally friendly natural material according to the present invention.

The present invention relates to a method of manufacturing a golf tee using an eco-friendly natural material, and more particularly, to a method for manufacturing a golf tee using a natural material such as rice and a mineral and a natural adhesive composition, The present invention relates to a method of manufacturing a golf tee using an environmentally friendly natural material which is capable of natural degradation to prevent environmental pollution, has excellent safety in use management, and increases productivity by cost reduction.

As shown in FIG. 1, the method of manufacturing a golf tee using an eco-friendly natural material according to an embodiment of the present invention includes a lengthening step S10, a mineral addition step S20, a mixing and stirring step S30, And a molding step S40.

The liquefaction step (S10) is a step of mixing the rice and water at the same weight ratio and slowly heating them at a temperature of 26 to 27 ° C to form a liquefied liquid.

In general, more than 80% of rice is composed of starch. When water is added to starch and heated to a certain temperature, the viscosity of starch particles swells and changes to a colloid state. This process is called "luxury". The liquefied liquid, which is the result of the lyophilization step S10, has an adhesive strength enough to be used as a natural adhesive depending on the concentration, and has an advantage that durability is increased at the time of solidification. This feature may be less durable than using a chemical adhesive. However, since the golf tee of the present invention is intended for seating a golf ball and is easily disassembled after being hit by a club, It does not need the same strong adhesive force and works as an advantage.

On the other hand, it is preferable to use brown rice or glutinous rice, which is superior in viscosity to general rice, as the rice used in the smoothing step S10. In general, the starch or the grains are generally pulverized so that the starch or the grains are easily pulverized. However, the present invention uses the rice in a granular state in a different manner. In particular, rice grains are soaked in water of the same weight ratio for 3 to 4 months and then heated to form a liquified liquid. This is because the cohesive force between the starch molecules is higher than that of the liquefied liquor in the powder state, There is an effect of suppressing the separation of water and powder when forming a suspension by adding a mineral powder. In addition, it has an effect of appropriately ensuring durability when solidified after cooling in the molding step.

In the mineral addition step S20, a silicate mineral powder is added at a weight ratio of 1: 1.2 to 1.4 to the gypsum obtained through the gypsum step S10 to form a suspension.

In general, silicate minerals are minerals made from salts of silicon dioxide and metal oxides, and are minerals that make up more than 90% of the crust. In this mineral addition step (S20), among the silicate minerals, talc or mica is selected and ground into particles of 200 to 500 mesh and added to the above-mentioned liquor.

The talc is a mineral which is used in various industrial fields because it has a low hardness and is easy to form fine particles, has soft feel and has heat resistance. Especially, it is useful as a filler in the production of paints, rubber, various spraying agents and wallpaper. The mica is also pulverized like talc and used variously as a filler and an adsorbent for various solvents. Therefore, in the present invention, talc or mica powder is added to the gypsum to act as a filler for golf tee formation.

The mixing and stirring step (S30) comprises mixing 30 to 36% by weight of cotton wool, 14 to 20% by weight of gum paste and 48 to 54% by weight of gelatin, and mixing the suspension obtained through the mineral addition step (S20) Are mixed at a weight ratio of 1: 2.2 to 2.5 and stirred.

The composition comprising the cotton swab, gum paste and gelatin is an element for imparting bonding force and adhesive force between raw materials constituting the golf tee, and it is possible to derive an optimal composition ratio only from natural materials that can be obtained in nature, And the mixture is stirred to form a mixed liquid to be introduced into the mold in an injection molding step (S40) to be described later.

The cotton wool has heat resistance and elasticity and is used in various fields. In the present invention, the fiber constituting the cotton wool is used to enhance the bonding force between the various components including the above-mentioned mineral powder particles, .

The gambling grass can be used as a natural vegetable gluing agent by utilizing the characteristics of saccharides contained in gambling, which is a species of seaweed native to the sea.

Natural adhesives refer to pollution-free grasses made from materials that have been extracted from natural materials for some time. They have less adhesive strength than general chemical adhesives manufactured by synthesizing various chemicals, but need to worry about side effects caused by various toxic substances contained in chemical adhesives There is no. Further, since the method of manufacturing golf tee according to the present invention does not require a strong adhesive force, it is possible to obtain a sufficient adhesive force between the components and a strength thereof by using a natural adhesive. In addition, it is advantageous in that it is less expensive than chemical adhesives, is relatively simple to manufacture, and does not cause environmental pollution.

Such natural adhesives can be classified into vegetable adhesives and animal adhesives according to the raw materials. Typical vegetable adhesives include seaweed paste and starch paste. In the present mixing and stirring step (S30), the gambling paste, which is made by heating seaweed called gambling among the seaweed grass, is made to be a composition together with the cotton swab. The gambling grass is known to be used for bonding mulberry fibers in the process of making Korean paper, and it has excellent compatibility with the cotton swab.

In addition to gambling, seaweed grasses can be made using seaweeds such as mugwort, chrysanthemum, etc. However, using the highest content of saccharides is most effective in exhibiting adhesion.

On the other hand, the gelatin is produced by using glue as a representative example of an animal adhesive among natural adhesives. Gelatin is an inducible protein that is extracted by heating collagen that constitutes animal tendon, bone, and leather for a long time, and is formed of a polymer material containing amino acid and formed into a translucent jelly state. Compared with vegetable adhesives, it has an excellent adhesive strength and quick curing.

Therefore, in the present mixing and stirring step (S30), the composition of the cotton swab, the gum paste and the gelatin is constituted at the optimum composition ratio in order to consider the characteristics of each raw material and effectively apply the adhesive force. In addition, the suspension obtained through the above-described composition and mineral addition step (S20) is mixed at a weight ratio of 1: 2.2 ~ 2.5, and stirred. If it is out of the range, an appropriate viscosity to be described later can not be formed. The strength of the finished product is excessively high or low so that the resultant product lacking the functionality as a golf tee has been produced.

In the injection molding step S40, the mixed liquid obtained through the mixing and stirring step S30 is injected into a golf tee mold, ejected, cooled, and then completed to complete the golf tee.

In general, injection molding is a method in which a thermoplastic synthetic resin is heated to melt, then injected into an injection molding machine, pressurized to a certain mold, and then cooled to form a molding. It is widely used for the production of plastic products mainly because it is simple in process and low in manufacturing cost compared to other forming methods.

In the present invention, an injection molding method using a synthetic resin melt as described above is introduced, and the mixed solution obtained through the mixing and stirring step (S30) is injected into a golf tee mold to be molded. This is because the above advantage of the injection molding method is utilized positively and the same effect as that of a general melt used in injection molding is induced in the mixed liquid obtained through the aging step (S10) to the mixing agitation step (S30) of the present invention And can be realized by characteristics.

In addition, in the present injection molding step (S40), the mixed liquid is pressurized to a mold, followed by cooling, followed by solidification through a cooling process, and a molded product is taken out. In particular, the completeness of the cooling process is determined It can be a key issue. This is also commonly used in injection molding using a general synthetic resin, in which a predetermined core is provided on a mold, and cooling water is circulated to gradually cool the mold. Such a cooling processing method is based on the fact that a synthetic resin melt which is formed at a high temperature of 100 to 250 ° C or more has frequent defects due to denaturation during cooling processing. Therefore, the above-mentioned cooling water circulation method is used as the most suitable cooling processing method.

However, in the injection molding step (S40) of the present invention, since the temperature of the mixed liquid pressurized in the mold is formed at 26-27 ° C, unlike the synthetic resin melt, the temperature change does not occur largely during the cooling process, Is low. Therefore, in the present injection molding step (S40), cooling processing by cold air blowing is carried out so that solidification and shrinkage of the molded article in the mold are induced at the same time, thereby facilitating the extraction. Therefore, the cooling time is remarkably shortened and the productivity of the whole process can be increased.

Embodiment 1 of the present invention will now be described with reference to the accompanying drawings. In the following description, a golf tee according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In the above-mentioned enrichment step (S10), glutinous rice and water are mixed at the same weight ratio, and after being soaked at room temperature for 3 to 4 months, they are gradually heated at a temperature of 26 to 27 ° C to form a liquified liquid.

Next, in the mineral addition step (S20), talc powder pulverized to 200-500 mesh is added to the liquor at a weight ratio of 1: 1.2 to form a suspension.

Next, in the mixing and stirring step (S30), a mixture of 33% by weight of cotton wool, 17% by weight of gum paste and 50% by weight of gelatin and the suspension are mixed at a weight ratio of 1: 2.2 and stirred to form a mixed solution.

Finally, in the injection molding step S40, the mixture is injected through a cooling process for injecting cool air after pressurizing the mixture to complete the golf tee.

On the other hand, in order to compare with Example 1 (the present invention), Comparative Example 1 comprising a manufacturing method of molding a golf tee by cutting a wood and Comparative Example 1 of a manufacturing method of molding a golf tee by extrusion using a synthetic resin 2.

The golf tees manufactured according to the method of Example 1 and Comparative Examples 1 to 2 did not cause any problem in use according to the purpose of golf tee. However, Example 1 was relatively high in the golf tee breakage rate after several times of tee shots because the club head used in the tee shot was closely related to the degree of damage by the golf tee. The possibility of reuse is high, but the impact applied to the club head is also increased. Therefore, it is necessary to select a manufacturing method in consideration of an appropriate level of strength in manufacturing a golf tee.

Particularly, since the golf tee used is scattered all over the field, it is impossible to collect and reuse the golf tee, so that the user's injuries caused by the fragments of the golf tee remaining in the field damaged, It is not preferable that a golf tee fragment having a high strength that can induce the golf ball is generated. Therefore, it is judged that the strength of the golf tee is the most appropriate level according to the method of the first embodiment.

In addition, in the test on the presence and the irritancy of toxic substances of the golf tee prepared according to the method of Example 1 and Comparative Examples 1 to 2, there was no such difference in Example 1 and Comparative Example 1 produced by the natural raw material However, in the golf tee of Comparative Example 2 using the synthetic resin raw material, it was found that the harmful environmental hormone and irritating odor appeared. However, as in Example 1, Comparative Example 1, in which a golf tee is produced using a natural wood as a raw material, is inferior in productivity as compared to Example 1 because the raw material is expensive and the manufacturing process is difficult and mass production is difficult It is expected that Example 1 will be more advantageous in price competitiveness.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It should be clarified. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
